The problem
You need a profile picture but your photo is landscape. You need a 16:9 banner but your image is 4:3. You need to cut out the left third of a screenshot. Every time, you end up either fighting with your OS's built-in photo editor or opening Photoshop for a two-second task.
Online croppers exist, but most of them make you drag an imprecise selection box with no way to type exact pixel coordinates. If you need a 400x400 crop starting at position (120, 80), good luck doing that by hand.
How it works
- Upload your image — drag and drop or click to browse.
- Choose an aspect ratio — presets for Free (unconstrained), 1:1, 4:3, 16:9, and 3:2. Or leave it on Free and drag any rectangle you want.
- Fine-tune with pixel input — type exact X, Y, Width, and Height values to position the crop precisely. The selection box updates live on the canvas.
- See what you're cutting — the area outside your crop is darkened so you can see exactly what stays and what goes.
- Download — the cropped image saves at the exact dimensions you selected.
All processing happens locally in your browser. No upload, no account, no waiting.
Common crop aspect ratios
- 1:1 (square): Profile pictures, Instagram feed posts, album art
- 4:3: Standard photo print size (8x6, 12x9), older TV/monitor ratio
- 16:9: YouTube thumbnails, widescreen monitors, presentation slides, LinkedIn banners
- 3:2: Standard DSLR photo ratio, 6x4 prints
- Free: When you need a specific pixel dimension that doesn't match a standard ratio
Crop vs resize
Cropping cuts away parts of the image — it changes what's in the frame. Resizing scales the entire image up or down — nothing is removed, just made larger or smaller.
If your image has the right content but wrong dimensions, resize it. If your image has extra content you want to remove (borders, background, unwanted objects at the edges), crop it. Often you'll do both: crop first to get the framing right, then resize to hit a target dimension.
After cropping, you can use the Image Resizer to scale the result to an exact size, or the Image Compressor to reduce file weight.
